RAILROAD-CAR Box-CASE AND-PEDESTAL.

' Sp-eccation of Letters Patent No.20,871, dated July 13, 1858.

To all whom *it may concern:

Be it known that I, JACOB ,0. GEISEN- -Hamilton and State of Ohio, vhave invented a certain new and useful Improvement in Railroad-Car Box-Cases 'and' Pedestals for Facilitatingthe Detaching the Case from the Pedestal; and I do hereby declare that in accomplishing facility of removal of the box case, the latter requisite has been overlooked.' This defect 'of stability or want of preservation of the vertical movement of' Athe box case will arise in all cases where a vibration or a swinging movement Is al- `lowed, which will produce a serious evil in the wear of the bearings by the twisting thereof, on the axle; by this defect,.the seat worn on one side irregularly, and is soon destroyed, rendering a change of boxes a' frequent occurrence whereverthe swung box case has been employed.

` In my improvedA construction of the box case and pedestal, I accomplish the foregoing object and results, and find on a prae- Vtical test that my box case isretainedin the jaws of the pedestal with all the advantages of the continuous groove, now in common use.

in providing my box case with projecting lugs, so that they may be entered through notches (corresponding in size with said lugs) formed in the jaws lof the pedestal; and allow of the bearing being placed'on the "axle, and then admitof the descent of the jaws by the lowering of the truck frame, the aforesaid lugs by passingbehind the projecting edges formed on the parallel faces of the jaws-of the .pedestal willsecurely retain he box case between the jaws (yet allow of the slight vertical movement consequent to use-of springs), when the weight of theitruck frame l&c. is thrown on When the box case is relieved of said weight by 'the raising of the jaws of the The nature of my improvement consists truck by jack screw or otherwise, the lugs of vthe box case will present themselves at' the openings or notches in the aws and readily A'admit of the removal of the box case without the necessity of'removing stay rods or drawingiof a bolt. f

The fol-lowing description and reference to the drawings will enable others to under# stand my improvement.

Figure 4 is a front view of a jaw-pedestal formed in the usual manner with the ex? ception ofv removing portions ofthe projections (a, a) on the faces of the jaws,- thus forming a notch or notches-(b b) on each ace.

A vis the ordinary gum spring with its cupv (seefFig. 6) which-is a side View of the box caseas connected with the pedestal and in its place in the'jaws with the weight of the truck on the axle. Fig. 5 is a side view of the pedestal.

Fig. lis a top view, Fig. 2 a side viewv and Fig. 3 a perspective view of the box case detached from the pedestal. It is formed in the usual manner, with the' exception that I have provided it with 'lugs or projections (c, 0,) on each side thereof of corresponding size to the notches (b) in the jaws of the pedestal; B is a portion ofthe axle.

By reference to Fig. 6, the maintenance 'of the vertical position of the box case is shown, the lugs (c c) being above and below the notch (b) of the jaw. It consequently gives the box full bearing in its whole length on the projection of'the pedestal, and in this way prevents all liability of. accidental displacement by an undue strain on a single lug of each side. i

Having described my improvement what I claim 'as my invention and desire tb secure by Letters Patent is- The employment of thelugs 0 c formed on box case D; when used in connection with the notches b b (two or more) formed in the. pedestal E substantially as described, for the purpose of readily detaching or removing the box from the axle, yet retaining the box case in a proper position in the jaws of the pedestal in thel manner set forth.

In testimony whereof I have hereunto signed my'name before two subscribing witnesses.
